Jack of Fables was a spin-off of the comic book Fables, both of which were published by DC Comics as part of that company’s Vertigo imprint. It shows the adventures of Jack Horner that take place after his exile from Fabletown in the Fables story-arc Jack Be Nimble (Fables #34 and #35). A preview of the series was shown in Fables #50, and the series itself debuted in July 2006.
It was written by Fables writers Bill Willingham and Matthew Sturges. Brian Bolland was the artist of this particular cover.
